Hi, I know what you mean. But behind scenes two files will still have a single entry in page cache. I am just not sure how the read-advice is applied to different mappings and how this interferes. Therefor I would have proposed to be on safe side and manage a single mapping inside Lucene. By that we have control over when which read advice is there for the mapped file (and the FS cache behind). I can do some investigations how this is handled in Linux (not sure about windows, macos) when multiple mappings on same file exists. -- This is an automated message from the Apache Git Service.
